A kind of slag sorting production method

Abstract

The invention relates to a process flow of a furnace slag sorting production device in the field of environmental protection. A material storage device is connected with a pulverizing device in a matched mode; the pulverizing device comprises an upper side powder outlet and a lower side particulate material outlet; the upper side powder outlet is coordinately provided with a pneumatic conveying device; the lower side particulate material outlet is coordinately provided with a conveying-out device; the pneumatic conveying device is coordinately provided with a dust removal device; the pneumaticconveying device coordinately enters the storage device and a finished product warehouse device through a conveying-in device; the lower portion of the finished product warehouse device is coordinately provided with a finished product output device; a flue gas dedusting device is arranged beside a feeding device; the feeding device is directly led to the flue gas dedusting device through a pipeline; and the flue gas dedusting device is coordinately provided with a quantitative water charging system and a quantitative gas charging system. The process flow provided by the invention facilitatesfurnace slag sorting, in the operation process, smoke generated by primary pollution and secondary pollution is treated in a centralized mode, secondary pollution is prevented in the furnace slag sorting process, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to a slag sorting production method in the field of environmental protection. Background technique [0002] According to different metallurgical processes, slag can be divided into smelting slag, refining slag and synthetic slag; according to the properties of slag, it can be divided into basic slag, acid slag and neutral slag; many slags have important uses; for example, blast furnace slag can be used as cement raw materials High-phosphorus slag can be used as fertilizer; vanadium-containing and titanium-containing slag can be used as raw materials for refining vanadium and titanium respectively; some slag can be used to make slag cement, slag brick, slag glass, etc.; It is composed of coal ash; it can be used as raw materials such as bricks and tiles; slag powder refers to the melt generated in the process of pyrometallurgy that floats on the surface of liquid materials such as metals, and its composition is based on oxides (sil...
